ABSTRACT:
A method and system for evaluating lead-acid battery jars in a battery backup or standby system applies, in a stepwise manner, a current load across a group of adjacent jars. Voltage measurements are taken across each jar in the group at various times during the application of the current load. These measurements are utilized to calculate the ohmic resistance, the charge transfer resistance and the double layer capacitance of each jar.
